Link hygiene is the practice of creating, sharing, and managing invitation links carefully to reduce unintended access. It matters when a link grants entry to a call or other resource, especially if guests can join through a browser without signing in to an account.
In practice, hosts should share links only with intended participants, avoid posting them in public or untrusted spaces, and use available controls such as expiration or revocation. Participants should check where a link came from before opening it. These steps do not replace authentication or access controls, but they help limit misuse if a link is forwarded or exposed.
